In the 2-phase separator process control is generally divided into 3 parts, namely readings natural phenomenon by the sensors, the data processing by the controller and execution order controllers by the control valve. To understand process control in 2-phase separator required a miniature separator together with their fittings which consist of sensors, controllers and control valve or commonly called mini plant. On the design and build this 2-separator mini plant using control valve with a DC motor as regulators of water flow. Used by 5 volt power supply with Tputar variation from 0 to 91.1 seconds as the control variable of the control valve. Characterization of the transfer characteristic control valve performed with 4 tests are: DC motor driver block test, DC motor block test (Tputar influence the degree rotary), the valve block test (degree rotary influence the percent valve opening), control valve on the 2-phase separator system test and the final testing of the influence of voltage variations on the characteristics of the control valve to see the dynamic characteristics of the control valve. Obtained from the testing of control valve characteristics for Tputar input range of 9,11 to 63,77 seconds, the output range from 7,49 to 98,53 ml/s, and the type flow characteristics is quick opening with a time constant 12,61 seconds.
